Starting a thread before wxPython bootup ... interesting.

[Shafik]

My apologies for not supplying more info, I am at work and I am
technically not allowed to surf the web for anything.

I am using Python 2.5.1,  the latest wx version (2.8.xx, I dont recall
exactly). This is running under windows XP under the latest version of
cygwin (that could be the source of the issues too).

I was just looking for a general way to approach wx and
multithreading, not a detailed solution to my problem. There are lots
of tutorials online that describe how to perform a time-consuming task
in a separate thread in a wx-gui, but nothing that describes any other
use cases.

The real goal is to start the gui in a different thread, and have the
main thread regain control. That seems like a feasible thing to be
able to do, though I have been unsuccessful ... if anyone would like
to suggest something without being covertly insulting, I'm all ears.


Thanks,
